A musical group sells hats at their concerts. After one concert, they sold 120 out of 200 white hats and 210 out of 300 black hats. Which ones are true? 60% of white hats were sold
70% of black hats were sold
A greater percentage of white hats were sold
A greater percentage of black hats were sold

The musical group sold  60%of the white hats and  70%of the black hats.

A greater percentage of  black hats were sold.

Step-by-step explanation: to answer this question we have to divide the number of hats sold by the number of total hats for each case.

Then, we have to multiply that result by 100, to obtain the result in percentage form.

White Hats: (120/200) x 100 =60%

Black hats: (210/300) x 100= 70%

The musical group sold 60%of the white hats and 70%of the black hats.  

A greater percentage of black hats were sold. (Since 70 > 60 )

(a) the volume of the cone is 20/3 in3
